Loss amount control method in solidified soil scouring protection construction of offshore wind plant
The invention discloses a loss amount control method in solidified soil scouring protection construction of an offshore wind plant. The method comprises the steps that the solidified soil strength corresponding to the maximum flow speed of fluctuation and ebb of each time in the construction period of a construction site of the offshore wind plant is determined; the initial setting critical flow velocity and the final setting critical flow velocity of the solidified soil are determined; estimating construction workable time and reserved solidified soil final setting time; when the actually measured flow velocity is lower than the initial setting critical flow velocity, solidification grouting construction is started, and solidification grouting is stopped at the construction operation termination time according to the reserved solidification soil final setting time; and the grouting is repeated for multiple times, and the stop time is waited for each time, so that the whole fan foundation scouring pit is filled with the solidified soil protection structure. The erosion pit evolution does not need to be monitored in real time, the method is simple, the cost is low, the loss amount can be effectively reduced, and the construction quality of the soil protection structure is improved.
本发明公开了海上风电场固化土冲刷防护施工中流失量控制方法，包括：确定海上风电场施工地的施工期内每次涨落潮最大流速对应的固化土强度；确定固化土初凝临界流速和终凝临界流速；估算施工可作业时间和预留固化土终凝时间；在实测流速低于初凝临界流速时开始固化注浆施工，并根据预留固化土终凝时间，在施工作业终止时间停止固化注浆；重复多次注浆，每次等待停歇时间，使得固化土防护结构填满整个风机基础冲刷坑。本发明无需实时监测冲刷坑演变，方法简单，成本低，能有效降低流失量，并固化土防护结构的施工质量。
